Using xilinx_axidma driver in Petalinux 2022 and Linux Kernel Version 5.15.19 #144

Hi, I am trying to use the xilinx_axidma driver in Latest Petalinux 2022 version and Linux kernel version 5.15.19 , since the driver was tested with 4.x kernel version I am getting the below errors when I compile the driver in Linux kernel version 5.x , do you have driver files with support for kernel version 5.x r can you suggest the changes I need to make for this to work.
